ppStreamData->Lock (crashing)

[Anddos]

I am trying to lock the vertex data in the DrawIndexPrimitive hooked function but for some reason its crashing..., does anyone know why?

typedefstruct d3dvertex_s
{
float x, y, z, rhw;
//DWORD color; //dont need atm
//float tu, tv; //dont need atm
} d3dvertex_s;
 
d3dvertex_s *m_pVertex;
 
m_pIDirect3DDevice9->GetStreamSource(StreamNumber,&ppStreamData,&pOffsetInBytes,&pStride);
sprintf(oBuffer,"%s %d\n","pStride",pStride);
outfile << oBuffer;
 
 
hr = ppStreamData->Lock(0,0,(void **)&m_pVertex, D3DLOCK_DISCARD); 
if(SUCCEEDED(hr))
{
sprintf(oBuffer,"%s\n","Lock OK");
outfile << oBuffer;
}

D3DLOCK_NOSYSLOCK

unless buffer was created with D3DUSAGE_DYNAMIC

go down to 'using dynamic vertex and index buffers'
